The invention relates to the field of energy gas adsorption and storage, and discloses a high-capacity methane storage material and a preparation method and application thereof. The preparation method of the high-capacity methane storage material of the present invention comprises the following steps: 1) in the presence of water, the acetate salt, the ferric salt and the divalent metal salt are subjected to a first contact reaction, and then a first solid-liquid separation is performed to obtain The first solid phase; 2) in the presence of an organic solvent, the first solid phase obtained in step 1) is subjected to a second contact reaction with a carboxylic acid ligand and acetic acid, and then a second solid-liquid separation is performed to obtain a second solid phase; 3 ) thermally treating the second solid phase obtained in step 2), wherein the carboxylic acid ligands include azobenzene-4,4'-dicarboxylic acid and 4,4'-stilbene dicarboxylic acid. The high-capacity methane storage material of the present invention has high chemical and thermal stability and high methane adsorption capacity. |
